Restart Open-Xchange

To restart Open-Xchange Server after the update, run

$ service open-xchange restart

You might want to check with

$ ps aux | grep open-xchange

that there is exactly one newly spawned process running Open-Xchange Server.

You should verify that login is possible. Upon the first connection after the backend update, you will get the message Error: updating database, try later. The second try should succeed.
